Traveled widths shall be a minimum of 10 feet. Shoulders shall be a
minimum two feet in width. Shoulders shall have a two-percent cross-sectional
slope. Shoulders shall not be impeded by obstructions (e.g., light poles,
mailboxes, trees, tree limbs, shrubs, etc.). A minimum of one shoulder shall
pitch away from the driveway to direct stormwater runoff off of the driveway.

The center-line grade for any driveway shall not be less than 0.75%
nor greater than 10%. The driveway intersection with a traveled way shall
provide a leveling area not to exceed three-percent grade from the edge of
the traveled way for a minimum distance of 30 feet. The driveways shall be
graded to not create low points within the driveway that will create puddling/icing
conditions.

Slopes abutting driveways shall not exceed 3:1 in fills and 2:1 in cuts.
Rip-rap slopes are allowed at a 1:1 slope. Vertical retaining walls are also
allowed. Guardrails may be required by the Board of Selectmen or its designee.

Driveways with slopes greater than 5% shall be constructed of three
inches of bituminous concrete placed in two lifts. Driveways with slopes less
than 5% do not have to specify surface cover. All driveways shall be of three
inches of bituminous concrete for a minimum of the first 20 feet or longer,
if so directed by the Board of Selectmen, or its designee, from the driveway
intersection. Concrete driveways shall be allowed as authorized by the Board
of Selectmen, or its designee, as directed by the Highway Surveyor, provided
that the concrete driveways provide an adequate friction surface to mitigate
skidding conditions.

The stormwater runoff from all impervious areas shall not discharge
into the public right-of-way. The peak rate of runoff at the street shall
not increase from the predeveloped rate during the two-, ten-, twenty-five-
or one-hundred-year storm event, unless an increase is authorized by the Board
of Selectmen, or its designee. Stormwater runoff may discharge directly into
rights-of-way of new subdivision roads if the overall stormwater management
plan for the street is designed to accommodate the runoff and a catch basin
is located within 10 feet of the downslope side of the driveway. The purpose
is to prevent ice jams in the winter.

Driveways shall be located and designed so as to minimize conflict with
traffic on public streets and to provide visibility and sight distances which
are safe and adequate for observation of approaching vehicles and pedestrian
traffic. Driveways on the same side of the street shall not be located within
100 feet of the edge of an existing driveway or 100 feet from the point of
tangency of a roadway intersection along the road that the lot has frontage
unless authorized by the Board of Selectmen, or its designee. A minimum sight
distance in all directions shall be provided as follows:

Strict compliance with the requirements of these regulations may be
waived when, in the judgment of the Board of Selectmen, or its designee, such
action is in the public interest and not inconsistent with the Code of the
Town of Groton.
